Changes in the social situation and the high economic growth in Formosa have been making the life of people richer, leading to a bewildering change in their life style. In this study, we aimed at grasping the actual living conditions of some Formosan pupils, together with correlation of their dietary life to their living habits. The following results were obtained. 1) The physique judgment by the Rohrer's Index revealed the prevalence of obesity in 12.1 and 6.7% of elementary school male and female pupils, respectively. 2) The family consisted of 5.0 f 1.5 members for the former school pupils, respectively, and two generations household was noted for 75.1%, respectively, indicating a transition to the nuclear family. 3) The habit of lack of a meal was noted to be as high as 12.2%, respectively. Lack of appetite and no time enough for eating were predominant reasons. 4) The frequency of taking meals with all the family was as high as 92.5% for dinner and as low as 4.9% for breakfest, respectively, enabling us to get a glimpse of the Formosan dietary habit. Pupils in a situation such that a child takes meals alone represented 25.5%, respectively, indicating an increasing tendency with advanced grade. 5) In terms of the dining-out habit, ca. 12.0% of the former school pupils had a habit of dining-out every meal, which was markedly composed of staple food such as noodle and bread. 6) In terms of the meal-taking frequency by food group, former school pupils showed a higher frequency of taking rice, bread, meat, processed meat, fruits, vegetables, eggs, milk and fat, suggesting a dietary tendency to the European style. 7) As to the result of factor analysis, two factors were extracted from both male and female, cumulative contribution rate accounted for 86.6 and 85.6% of the variance and revealed a fairly similar dietary pattern for the former school pupils. 8) In terms of overall healthiness judgment, as low as 18.8%, were judged healthy, compared with as high as 37.8%, judged unhealthy respectively, with no sex difference being observed.
An exploratory study using a health diary was made to inquire into health problems and illness behavior of inhabitants in a gradually depopulating mountain village with a heavy snow fall in Niigata Prefecture. Seventy-eight inhabitants (aged 4-79) completed a health diary for one month each starting in winter, spring, summer, and autumn . The results of an analysis of their health diaries (9, 516 person-days in total) were as follows: 1) Main events in everyday life in each season were, in winter, snow removing, in spring, rice-planting, in summer, events related to Bon (the Bunddhist All Souls' Day), and in autumn, rice harvesting. 2) Typical health problems in each season were, in winter, headache, and lower back pain, in spring, lower back pain, in summer, fatigue, and in autumn, headache, and lower back pain. 3) It was suggested that occurrences of these problems had something to do with a unique life event as well as a natural enviromental condition in each season in the area concerned. 4) A total of 541 problem episodes (6.9 per person) were recorded with 54.1 percent of the episodes taking no form of medical action, and 25.1 percent of the episodes taking only a patent medicine. A percentage of the episodes visiting a doctor or a dentist at least once in an episode was 13.5. 5) Patterns of illness behavior were different by sex, age, and contents of health problems. 6) A health diary was supposed to be an effective method of inquiring into health problems and illness behavior in everyday life.
Japanese history of eugenic protection law was reviewed. Involuntary sterilization was especially focused. A review of proceedings of the National Diet, statistical reports, and medical papers were performed, as well as interviews. Before the end of World War II, "Kokumin-Yusei-Hou" was enacted. The reasons were as follows; One was negative eugenics, which aimed to reduce the "defective" persons. The other was political incentives to forbid family planning movement in order to obtain more population. On the contrary, after the war, "Yusei-Hogo-Hou" was enacted, mainly because of family planning. The number of application of sterilization has constantly decreased, however, several different patterns were observed. 1) The speed of decrease of the sterilization for maternal or medical reasons were ceased after the 1970's. 2) Involuntary sterilizations have gradually decreased to none. 3) Involuntary sterilizations for the mentally ill were constantly applied until the 1970's. The issue of translation, the reasons of the changes, and the application to the mental retarded are discussed.
